[1] NECESSARY REPAIRING TOOLS Description Hex wrench 8 Plastic hammer Use for Removing /mounting Keylss drill chuck Removing Keyless drill chuck [2] LUBRICATION It is not required to lubricate the gear section. Use Makita genuine Gear assembly that is factory-lubricated when repairing. [3] -1. Keyless Drill Chuck DIS Note: (1) It is required to remove Keyless drill chuck at first when replacing. When parts other than are related to repair, removing Keyless drill chuck is not required. (2) If it is impossible to remove Keyless drill chuck in the following manner, use 1R359 (Chuck removing tool) to remove it. Refer to Makita repair tool list. Fig. 1 1) Open the jaws of Keyless drill chuck fully, and remove M6x22 - Flat head screw (left-handed and threadlocker coated) by turning clockwise using cordless impact driver in Forward rotation mode with slotted bit. 2) Fix the short leg of a hex wrench 8 in Keyless drill chuck, then clamp the long leg of the Hex wrench 8 securely in vise. 3) Set Action mode change lever of the machine in Drill mode, Speed change lever in Low speed, and F/R change lever in Reverse rotation mode. 4) Install Battery and hold the machine securely with both hands, then remove Keyless drill chuck from by pulling Switch trigger slowly to minimize the impact of kickback. (Fig. 1) Important: The machine rotates in the direction of the arrow with very strong force at the moment when Switch trigger is pulled. Therefore, be careful not to pinch your hand or finger between the machine and the vise. Note: Clamp the flats of Hex wrench 8 securely in vise. 1) Turn Keyless drill chuck clockwise until it sits on the end of the threaded portion of spindle of. 2) Hold the short leg of Hex wrench 8 with Keyless drill chuck, and fix the long leg of Hex wrench 8 in vise. Install Battery. Then set Action mode change lever of machine in Drill mode, Speed change lever in Low speed, and F/R change lever in Forward rotation mode. 3) Slowly pull the switch trigger to rotate spindle until the motor is locked. Important: Be sure to release the switch trigger just after Spindle is locked. 4) Secure Keyless drill chuck with M6x22 - Flat head screw by turning counterclockwise using cordless impact driver with slotted bit. Note: If you reuse the removed M6x22 - Flat head screw, apply threadlocker (ThreeBond 1321B/ 1342 or Loctite 242) to the threaded portion.
